Too much light for seedlings (uncapped LED bulbs)

[cannn]

Fox farm nutrient line up is a blessing for us newbies. Id seriously suggest getting it.

That was my first nutrient line. It certainly works if you know how and when to use it. I dont know about the feed schedule though. Whenever id use it my plants went through hell. Theyve been better since i abandoned it and trusted myself

 

[Angus Hung]

I dont think those plants need nutrients yet after you get the first few sets of leaves is when i start lightly feeding with
something like a 1-1-1 then when they start haveing full normal leaves i start with the 4-4-4 . its hard to say what the moister content of the cups at 170grams would be. maybe 170 is to much or not enough?

At this point we are looking to nutrients because the plants are growing so slowly... Wouldn't CalMag be the only other nutrients we would need in addition to the nitrogen, phosphorus and potassium?

 

[cannn]

Calcium, sulfer, magnesium, boron, iron, manganese, zinc, copper and molybdenum

Like we've said you need to invest in a nutrient line like the foxfarm trio that includes all the necessary macro and micro nutrients. Npk is very important, the 3 most important, but you cant ignore the rest

Also the product calmag is mainly calcium. Epsom salts are better for adding magnesium and sulfer

We are now watering when the cups get down to a weight of 170 grams. This happens about every 3-4 days.

Plants are 25 days old.

Starting this morning, we introduced 1/4 strength 5-5-5 organic fertilizer. That will now be consistent.

Sorry man but do u weigh ur pots lol

 

[Mass Medicinals]

So right now weighing them is an easy step in determining if the pot is dry or not. Also we are seeing a major improvement since introducing the 5-5-5 nutrients. In 2 days we have seen the plants nearly double in size. The ones that were appearing to be dead are now getting the green back.

There are a couple variables that need to be considered. One the temperature is currently running in the 70's, and the plants are now getting food. It appears both are helping to promote solid growth. Fingers crossed all this stress on the seedlings doesn't force them to go herm on us.

So we just looked at the fox farm trio. Isn't our 5-5-5 nutrient nearly the same as FoxFarm 6-4-4 GrowBig? So all we need for veg stage is the supplemental nutrients from something like BigBloom?

We would really like to find Veg / Flower nutrients that are not liquid. Preferably a all-in-one package that contains the main NPK as well as the other essentials.

So, I've never completed a grow yet, on my first one...(rest of this, grain of salt ) but I've read enough to pick out a few things in what's going on here.

Your watering schedule is not correct for seedlings. Do some searches on these forums, and look for youtube videos(relevant, recent) on watering schedules for seedlings (type in water seedlings cannabis, and the first 3-4 videos are worth watching).

For coco, aka soiless grow medium, nutes need to be used right out of the gate. You don't need nutes for seedlings in soil because the soil has all the nutes they'll need during the seedling stage. For coco, it has nothing besides the ability to retain water.

For lighting height... it's tough to tell because of all the stress they are under with overwatering and no nutes. Getting those under control will allow you to hear what they are telling you about the lights.

Your last update seems to have gotten better(post some pics!!).

To figure out light height after that, with my seedlings, I've been monitoring stretch... if they are growing UP too fast(qualitative based on looking at many MANY videos and photos of seedling day by day development... check this site's grow journals!), I lower the light... if they are short and stubby(aka no stretch)... I raise the light a bit so they stretch. If they are stretching a bit, and the plant development is "normal" height for age... you'll be fairly safe for light height. This may be a bit tougher because of all the stunting from the stress... but gauge where they are when they become healthy, and go from there.


Finally, I've been reading a TON preparing for this grow. One thing that I've picked up on, if you want to have a good grow, you can't stick to exact schedules and precise measurements only. Care for your girls, listen to what they say, and give them what they want.

Don't love them too much!

Good ole farmers market 50lb sacks of base and you mix up ratios.

Very cool GH: Maxigrow, Maxibloom. Sound like exactly what we want and need for the grow. One product for veg the other for boom. And just monitor the plants to see how they are handling the feeding.

Thanks!!!!!

We have 5-5-5 right now. Can this be switched out immediately for Maxigrow? Also do you recommend ph Up & Down for these types of nutrients? We don't have a ph testing machine, and were hoping to just triage if and when the plant starts showing signs of issue.

You can switch anytime. Get silica for pH up and reg pH down. Maxi x sets pH low sometimes. Silica will raise pH and help thickness. Get both my friend. Better to have options than none. Botanicare silica is 15$ pH up is 15$ a qt or 26 a gallon.


Bro you gonna have to bite the bullet and get scientific testing gear as in, pH testing gear. Cheap pen on Amazon cost 5 bucks and takes 12 days to come, I bought 10 of them last time. I can try and link you to one.

Don't wait for issue's to show because some are fast climber's and you are not gonna like watching your plant yellowing and necrosis at hi speed. Proactive Is better than reactive.

Epsom salts@ 1 gr per gallon if in Coco.

Maxi @ 1 level scoop (small side) per gallon sets around 1.7 EC (850 ppm)

Going by my own recent experience 12 inches from a decent LED is too close, back it down a bit

 

[Mass Medicinals]

The fertilizer is really kicking these seedlings into full throttle!!!!!!!

Check out what has happened in just 6 days. We are really breathing a little sigh of relief (and mentally preparing for the next issue).

Day 15 (too much water, too much LED, and no nutrients)

Day 25 (without any nutrients)

Day 31 (with 2 rounds of nutrient feeding)

Our newest issue is possible stretching. SUCH a wonderful issue to be having, rather than seedings dying
We are specifically talking about the lower left solo cup. It is the only seedling with an inch of stem between nodes. We reduced the distance between the lights and plants. It is approximately 20 inches reduced down from ~24 inches. Should this particular cup be raised even closer? The strain stretching is super hash plant. The others are super silver haze and northern lights. Perhaps it's just the healthiest.

Items that still need to be purchased:
- pH pen or other electronic pH testing device
- 600 Watt MH/HPS (was purchased but arrived damaged)
- 6 inch duct fans / 6 inch ventilation duct
- Maxibloom & MaxiGrow
